P025 Lens and Optics

Front

DIGITAL ZOOM

Back

A camera feature that crops the image to a smaller size, making it appear larger, but resulting in a loss of quality.

Front

OPTICAL ZOOM

Back

Zoom feature moves the glass in the lens (elements) to change the magnification and angle of view (image size) without affecting the quality.

Front

FOCAL LENGTH

Back

The distance between the optical center of the lens and the focal plane, and it determines the magnification, compression and angle of view of an image.

Front

IMAGE STABILIZATION

Back

A lens feature to reduce blurring that is caused by slight movements of the camera during exposure at slower shutter speeds.

Front

LENS FLARE

Back

Lens flare appears as round hazy artifacts in an image due to internal reflections inside the lens when pointed toward a bright point of light.

Front

LENS SHADE

Back

A device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare.

Front

NORMAL LENS

Back

A lens that reproduces a field of view that appears 'natural' to a human observer.

Front

TELEPHOTO LENS

Back

A lens with a focal length that is longer than normal. As a lens gets more telephoto, its magnification increases and its angle of view decreases.

Front

WIDE ANGLE LENS

Back

A lens with a focal length that is shorter than normal. As a lens gets more wide-angle, its field of view increases.

Front

MACRO LENS

Back

A special type of lens or lens setting used for photographing objects at extremely close distances.
